When the dealer sent my car to a body shop to have paint chips fixed, they reshot the hood with clear after blending it in.
When I got it back, it looked horrible - a few shades "lighter" - however, it was due to *really* bad polish by the shop...halo'ing, swirl marks, etc...looked like crap in sunlight.
I complained and they fixed most of it. I had it detailed after that and perfection.
Then I drove it the next day and got a chip in the bumper
